A/C codes


What job

Recommended Posts

Hello to all,

New here to this site.

I'm in kind of a tight binder.

Have this 94 SLS that I just bought as a back-up beater off the eBay. (keep the nice one in over the winter)

Turns out it's a darn nice car for the age and miles.

Who ever had it took good care of it. Anyway, I'm 2000 miles from home and am having problems with the A/C system.

Can anyone tell me what the A12 code means?

I've replaced the compressor,dryer,orfice,and flushed the system out.

For some reason the compressor will not come on unless it is given direct power from the battery. This I do not like doing.

The system would not take the freon in as it should either and is running very high pressure on the low side. 100 psi at compressor off position.

Entry side of evaperator after the orfice is icing up like it is blocked.

This system was not working when I bought the car so I know there was problem, I did power up the compressor before taking it down. The system worked but I did not like the sound of the compressor but it did have cold air.

The system was a mess but cleaned out very well.

Of course the replace engine soon light will not go off either and I think this A/C problem is the cause. There are no other codes in the PCM.

My problem is I do not have what the A/C codes mean along with me. (can't take the whole shop along)

I've cleared all the codes but the A12 keeps comimg back.

Thanks for any help folks. Hate being down while on the road. <_<
